You can control Servo and change appearance/traits!!! Yay!

At least TS4 servos are more customizable than TS1 or TS2 servos, or the TS3 simbots. I agree that they do resemble Plumbots a bit, but without the wide variations in appearance or in microchip types. I do remember how disappointing TS3 Simbots were (one reason why they were redone as Plumbots I think); basically their motives (with the exception of Hygiene) were the same as those of regular sims, just with different names, and they could sleep in beds. These servos will at least be miles better than that. I really like them in part because they have unique motives (Charge and Durability), can wear out and break, and can't tolerate water, which makes them very different from regular sims. I wonder if they can recharge in the sun like the TS2 servos. Their animations and appearance also look really excellent.
